It is suitable to detect PD flaw and locate PD signal for switch cabinet etc.Features Built-in ultrasonic sensor; electrical fault generates ultrasonic wave at the fault point, and ultrasonic mode transmits the ultrasonic signal through the earphone to scan the area to detect the discharge. Various characteristics of vibration, pop, and hum can be associated with different faults. Built-in high-precision TEV sensor, coupled with electromagnetic signals generated by partial discharge, to identify potential internal discharge failure risks. In Ultra Mode, the main interface displays the partial discharge amplitude (dBuv), and uses the yellow, green and red colors to increase the severity of the partial discharge. At the same time, the headphone listening volume (Vol) can be adjusted. In the transient radio mode (TEV Mode), the main interface displays the partial discharge amplitude; the number of pulses, the total number of pulses and the discharge intensity level in each power frequency cycle. Powered by rechargeable lithium battery, continuous working for more than 6 hours. True color LCD display, real-time battery power prompt; physical film button is easy to use and equipped with external high-fidelity noise reducing headphones. Adopting a color LCD screen, using a graphic and digital display mode, it is possible to intuitively know whether the partial discharge amount exceeds the standard. Simultaneously integrate the two methods of transient ground wave and ultrasonic to facilitate on-site use. It can detect various discharges in electrical equipment such as medium and high voltage switchgear (3~66kV) and is suitable for many different types of power equipment.Specifications TEV SensorMeasurement range0-65dBBandwidth3-100MHzAccuracy±1dBMax. pulse times per cycle1000Min. pulse times1 Ultrasonic sensorMeasurement range-7dB~70dBResolution1dBAccuracy±1dBSensitivity-65dBCenter frequency40.0±1.0KHzBandwidth2.0KHz Ultrasonic wave condenser(OPTIonAL EXTRNAL)Gain10dBSensor center frequency40kHzSensor bandwidth2kHzLaser sensor5mW 650nm red laser; safety class LASS IIIAInterface4-core aviation plugCable2 m spring wire Serpentine probe ultrasonic sensor(OPTIonAL EXTRNAL)Sensor center frequency40kHzSensor bandwidth2kHzSensor sensitivity-65dBInterface4-core aviation plugCable2 m spring wire BatteryBuilt-in batteryLithium battery, 8.4V, 1800mAhUse timeabout 8hoursCharging timeabout 4 hoursProtectionOver-voltage and over-current protection ChargerRated voltage8.4VOutput current1ATemperature-20ºC-60ºCHumidity<80% HardwareShellMonochrome molding plasticScreen240*320 TFT LCD screenControl6 buttonsInterfaceMicro USB interface, charger port, headphone port, external port for collecting wave collectorHeadphoneHigh fidelity noise canceling headphones DimensionSize178mm×75mm×30mmWeight0.25KGCase size399mm×295mm×105mmCase weight2.3KGTotal weight2.7KG Working environmentUse temperature-20ºC~50ºCEnvironmental humidity0-90%RHIP class54
